About Commands

Commands are objects that describe formatting operations. For example, the bold command.

Commands tell Scribe:

• how to format some HTML when executed (similar to document.queryCommand);
• how to query for whether the given command has been executed on the current selection (similar to document.queryCommandState);
• how to query for whether the command can be executed on the document in its current state (similar to document.queryCommandEnabled)

To ensure a separation of concerns, commands are split into multiple layers. When a command method is called by Scribe, it will be filtered through these layers sequentially.

Scribe

Where custom behaviour is defined.

Scribe Patches

Where patches for browser inconsistencies in native commands are defined.
